Kant, as we all know, compared moral law to the starry heavens, and found them both sublime. On the naturalistic hypothesis we should rather compare it to the protective blotches on a beetles back, and find them both ingenious. Arthur J. BalfourFoundations of Belief.

Morality without religion is only a kind of dead reckoning,an endeavor to find our place on a cloudy sea by measuring the distance we have run, but without any observation of the heavenly bodies. LongfellowKavanagh. Ch. XIII.
